Atomic frequency standards are very stable and accurate frequency sources. They are now used, for example, in high-speed communication, in navigation systems and in time-keeping. This study, which examines present knowledge regarding the operation of such devices, is designed to be used by the newcomer to the field as well as by the experienced researcher.

The Quantum Physics of Atomic Frequency Standards: Recent Developments, Second Edition, covers advances in atomic frequency standards (atomic clocks) from the last several decades. It explains the use of various techniques, such as laser optical pumping, coherent population trapping, laser cooling, and electromagnetic and optical trapping, in the implementation of classical microwave and optical atomic frequency standards. It provides an up-to-date, in-depth view of the vast improvements to atomic clocks that have occurred in the last 25 years. The improved stability and accuracy enable the verification of physical concepts used in fundamental theories, such as relativity, as well as the stability of fundamental constants intrinsic to those theories. The book first discusses improvements to conventional atomic frequency standards, highlighting the main limitations of those frequency standards and the physical basis of the limitations. It then describes how advances in the theory and applications of atomic physics have opened new avenues in frequency standards. The authors go on to explore the research and development of new microwave and optical frequency standards before presenting the results in frequency stability and accuracy achieved with these new frequency standards. They also illustrate the application of atomic clocks in metrology, telecommunications, navigation, and other areas and give some insight into future work. This new edition examines updated developments on the frequency standards, alongside content on the International System of Units (SI) and the role of atomic clocks on their base units. It also features new material on Coherent Population Trapping and new developments in the field of optical frequency standards. Key Features: Describes the basic physics, including quantum mechanics, behind the operation of atomic clocks. Explores new frequency standards that provide better stability and accuracy than older, more conventional standards. Discusses the importance of the field in the general context of physics. Jacques Vanier is retired from the National Research Council of Canada and as adjunct professor in the Physics Department at the University of Montreal. He is a fellow of the Royal Society of Canada, the American Physical Society, and the Institute of Electrical and Electronic Engineers. He has written more than 120 journal articles and proceedings papers and is the author of several books on masers, lasers, and atomic clocks. His main research work is oriented toward the understanding and application of quantum electronics phenomena. Cipriana Tomescu is retired from The Institute of Physics, Bucharest, Romania, and as invited researcher in the Physics Department at the University of Montreal. She is the author of numerous articles in scientific journals and conference proceedings. Her research involves state-of-the-art atomic frequency standards and H masers.

Atomic frequency standards provide the most accurate measurements in physics. The Quantum Physics of Atomic Frequency Standards is an extensive survey of the subject covering both theoretical and experimental aspects together with applications. As an accessible and essential reference it will be invaluable to experienced researchers and beginners alike. The first volume begins with a quantum mechanics treatment of the interaction of static fields and electromagnetic radiation with atoms and molecules. Each of the important phenomena - noise, relaxation, broadening and frequency shifts - is treated in detail and optical pumping and population inversion are explained. With all the background material now in place the major part of these volumes is devoted to a theoretical analysis of the operation of the numerous atomic frequency standards that are either in use, are being studied or have been proposed. * Caesium atomic beam frequency standards * Hydrogen maser * Rubidium frequency standards * Mercury ion trap * Frequency stabilized lasers In the final chapter the authors discuss the impact of atomic frequency standards on navigation and communication systems, in industry, in new technology and on fundamental research.

Metrology is the study of measurement. It includes all theoretical and practical aspects of measurement and may be divided into three subfields: Scientific or fundamental metrology concerns the establishment of measurement units, unit systems, development of new measurement methods, realization of measurement standards and the transfer of traceability from these standards to users in society. This handbook contains articles dealing with general topics of measurement and articles on particular subjects in mechanics and acoustics, electricity, optics, temperature, time and frequency, chemistry, medicine and particles. The contributions of the first part are sumamrized as follows. Introduction Units Fundamental Constants Fundamentals of Materials Measurement and Testing Measurement of Mass Desnity Measurement and Instrumentation of Flow Ultrasonics Measurement of Basic Electromagnetic Quantities Quantum Electrical Standards Metrology of Time and Frequency Temperature Measurement Metrology in Medicine

Due to steadily improving experimental accuracy, relativistic concepts – based on Einstein’s theory of Special and General Relativity – are playing an increasingly important role in modern geodesy. This book offers an introduction to the emerging field of relativistic geodesy, and covers topics ranging from the description of clocks and test bodies, to time and frequency measurements, to current and future observations. Emphasis is placed on geodetically relevant definitions and fundamental methods in the context of Einstein’s theory (e.g. the role of observers, use of clocks, definition of reference systems and the geoid, use of relativistic approximation schemes). Further, the applications discussed range from chronometric and gradiometric determinations of the gravitational field, to the latest (satellite) experiments. The impact of choices made at a fundamental theoretical level on the interpretation of measurements and the planning of future experiments is also highlighted. Providing an up-to-the-minute status report on the respective topics discussed, the book will not only benefit experts, but will also serve as a guide for students with a background in either geodesy or gravitational physics who are interested in entering and exploring this emerging field.

A wide-ranging review of modern spectroscopic techniques such as X-ray, photoelectron, optical and laser spectroscopy, and radiofrequency and microwave techniques. On the fundamental side the book focuses on physical principles and the impact of spectroscopy on our understanding of the building blocks of matter, while in the area of applications particular attention is given to those in chemical analysis, photochemistry, surface characterisation, environmental and medical diagnostics, remote sensing and astrophyscis. The Fourth Edition also provides the reader with an update on laser cooling and trapping, Bose-Einstein condensation, ultra-fast spectroscopy, high-power laser/matter interaction, satellite-based astronomy and spectroscopic aspects of laser medicine.
